Apologies, I missed the note explaining the commands (not sure how I missed it, I was looking for it before I posted). Works for me.

Prefix changed to /usr as I pointed out earlier. It is not seperate from /usr as long as headers are a symlink to /usr/include and without those symlinks some packages build may fail. Also, not really part of Xorg, but used by Xorg. Can also be used by Wayland which does not use Xorg. Also, I haven't yet got time to check how to disable llvm with current instructions, but I'll work on it later.
